i've had that happen a couple of times. no permanent damage to my fitteds. if you have a lot of fleece inners you might just prefer to rewash, but it didn't hurt my velours, sherpas, etc.

Yeah that! Adding if you have mostly pockets I would go ahead and rewash them on hot with a bit of dawn and that should take care of it. But fitteds are no big deal they just won't absorb quite as much if you use them now.
